Truck will shift from 1-2 only if I let my foot off the gas completely, overdrive light is flashing, no codes on obd,2005 Ford explorer sport trac 4.0;
How can I tell when my trasmission fluid is full on the dip stick?
If the OD light is flashing then you have faults, it maybe the scan tool can't read the Trans control module codes.

This may be because the transmission has a problem. It is trying to save itself from further damage by self-disengaging the O/D.
Please take this vehicle in for warranty service (if available) or to a trained mechanic/transmission shop for evaluation. Continued driving could further damage the tranny.
Good Luck.

This is likely your electronic speed sensor. The part costs about $60-$70 and is a relative quick fix for a mechanic.

Generally when the OD light flashes its stating that theres something wrong with the transmission.
Explorers were notorious for their transmissions having problems after wear and tear. Being 10 years old i wouldn't doubt that the valve body is going on it. I'd get the valve body checked out.
Be weary, if the car starts feeling like it cant accelerate but the RPM is increasing, that means your transmission is going bad.
Check Fluids for volume and color. If it looks really dirty or low, i'd add some fluid or get it flushed and see if that helps. If it doesn't the transmission will need to have its trouble code checked and have valve body looked at.

The coil-on-plug. These are common to fail. #1 is easy to get to, all you need is a 7mm socket, an extension, and a ratchet. P0301 tells you that cyl.#1 is not firing everytime it is asked to, P0316 means that during the first 1000 revolutions when you start your truck, there was a misfire. To be sure about the coil, swap the coils with the one next to #1. Clear the codes and wait for the codes to return. If the code P030_ shows up, (P0302 if you swapped it with #2, P0303 for #3, for example) Then remove that coil and get you another!

Transmission Control Switch (TCS)
The transmission control switch (TCS) is a momentary contact switch that allows the driver to cancel operation of 5th (overdrive) gear.
The TCS is located on the end of the selector lever.
When the driver initially presses the TCS a signal is sent to the powertrain control module (PCM).
The PCM uses the shift solenoids to disengage/disable 5th gear operation and activate the coast clutch.
At the same time the PCM illuminates the transmission control indicator lamp (TCIL), to notify the driver that 5th gear is canceled.
When the TCS is pressed again, 5th gear operation is enabled, the coast clutch is released and the TCIL is turned off.
Whenever the ignition is cycled (vehicle shut off then started again) the TCS is turned off and 5th gear will be enabled, even if the TCS had been on when the ignition was shut off.
Transmission Control Indicator Lamp (TCIL)
The transmission control indicator lamp (TCIL) is located in the instrument panel and is labeled O/D OFF. It is illuminated in conjunction with the transmission switch (TCS).
The TCIL will flash if the EPC solenoid circuit is shorted or a fault has been detected in a monitored sensor used for transmission operation.
Powertrain Control Module (PCM)
The operation of the transmission is controlled by the powertrain control module (PCM). Many input sensors provide information to the PCM. The PCM then controls actuators which determine transmission operation.
